The front office has one more week to take the roster down to 53.

One of the biggest questions -- whether Detroit will keep two or three quarterbacks on the roster this season -- remains to be answered.

Lions' coach Jim Caldwell was reminded Monday that, as a head coach in the NFL, he has kept three quarterbacks just once. He insists there is no theme there to be gleaned and applied.

"Every situation is absolutely different," Caldwell said. "Oftentimes you find that long-held theories and beliefs don't hold true depending upon the squad. Sometimes you're going to have a player that you consider more value to you at another spot that you'd like to keep so therefore maybe you take one less quarterback. Or, you figure that there's a quarterback that's really been doing extremely well and we'd like to have him as our third and he can help us, so you have to make a decision based on that. We'll look at those as our squad starts to take shape here the next few days.

"Whether or not we keep two or three, it just depends."

The obvious guy on the chopping block is Kellen Moore, who despite throwing the game-winning touchdown in a 13-12 preseason win over Cleveland is firmly behind No. 2 quarterback Dan Orlovsky on the depth chart.

Moore has experience with the franchise and could be insurance should something happen to starter Matthew Stafford or Orlovsky.

But with only 53 spots available, one could argue that the Lions could squeeze more value out of another position. While a third quarterback who knows the offense may seem more valuable than a sixth receiver, a linebacker or defensive end who can also contribute on special teams can be incredibly useful.

Either way, Moore isn't letting it get to him. It's a position he's been in every year since coming out of Boise State.

"I really don't worry about it," Moore said Monday. "The bottom line is just try to play well in the preseason and let the chips fall. Live action matters, but you kind of got to figure it out for yourself on the field. We'll see what happens; I'm not too worried. Whatever happens happens. You play one preseason, you figure something out."

In three preseason games, Orlovsky has gone 29 of 46 for 216 yards with no touchdowns or interceptions.

Moore has gone 18 of 23 for 189 yards, one touchdown and no interceptions. His attempts have decreased by half each successive preseason game. Thursday, in the the Lions final exhibition at Buffalo, both backup quarterbacks will get increased snaps.

"It's one of those things where you anticipate one of those guys is going to get the most time they've had any any point in time," Caldwell said. "I'm sure Kellen will at this particular point. We'll take a look at them, see how they do, see how they manage the offense, how they handle it, see how they move the ball, see how well they throw it. There'll be a pretty good opportunity to show themselves."
